MEANS AND METHOD 0F STORING AND TRANSFERRING GRESE T0 GREASE GUNS.

Application led February 10, 1922. Serial No. 535,601.

To all whom t may concern.'

Be it known that I,\IIENRY E. ELROD, a citizen of the United States, anda resident of Dallas; in the county of Dallas and State of Texas, haveinvented certain new and useful Improvements in Means and Methods ofStoring and Transferring Grease to Grease Guns, of which the followingis a specification. i l

My invention relates to means and method of storin and transferringgrease to grease guns an has for its particular object to provide meansfor accomplishing this in a convenient, uick and economical manner.

. Recently systems of lubrications have come into vogue which employ agrease gun in the form of "a container to one end of which is attached adelivery tube for connection with the bearing to be lubricated. Thegrease is forced from the gun by means of a screw plunger which enablesconsiderable pressureto be exerted upon the grease, which results in anefficient lubrication with but slight eEort. I f

One of the outstanding advantages attributed to these systems oflubricating is that ythe operation may be accomplished without soilingthe hands of the operator and without a waste of grease.

These features are obtained but difficulty is experienced intransferring a supply of grease to the gun and during this loading ofthe gun the hands of the operatorV are often soiled and a certainpercentage of the rease usually wasted.

Terefore the particular object of my invention isV to provide acontainer for the grease which is capable of being quickly andconveniently. secured to the grease gun whereupon the contents of thecontainer may be easily transferred to the gu'n.

The construction of my improved container therefore adapts itself to amethod' of transferring grease to the gun which enables this heretoforedifficult operation to be accomplished in a cleanly manner and with noloss of grease.

An embodiment of my invention is described and illustrated in theaccompanying specificationy and drawings so that those skilled in this(particular art may readily appreciate the a vantages thereof.

In the drawings:

Fig. 1 is a 'sectional view f my improved inventionattached to a greasegun,

Fig. 2 is an enlarged longitudinal section through the container,

Fig. 3 is a detailed sectional view of a modification of the container,

Fig. 4'is a similar view of another modification, and

Fig. 5 is a similar view of still another modification.

Referring now more particularly to Fig. 1 it will be seen that there isillustrated a grease gun comprising a container 10 to one end of whichis secured adelivery tube 11 the delivery nozzle 12 of which is adaptedto be connected to the part to be lubricated. In

practice the grease is forced from the container 10 by means of aplunger operated by a rod threaded in a cap which cap in turn is screwedon to the end of the container 11, screw threads 13 bein shown for thispurpose. The plunger, ro and cap are o mitted from the drawings.

The container of my improved invention comprises a cylindrical body 14open at both ends and adapted to be closed at one end thereof by a cap15 fitting snugly over the end of the container. The inner circumferenceof the container adjacent the end thereof is coated with a layer of tinor lead or other similar material 16 so that the container' 14 may beconnected to the grease gun 10 by screwing the same onto thescrewthreads 13 of the grease gun, the layer of tin or lead beingsufficiently soft to take hold of the threads of the grease gun.

The other end of the container 14 is bent over as at 17 to form acircumferential slot to receive the edge of a cupped disc 18 which is ofsuch diameter as to fit within the container and be slidabletherethrough. The disc-18 besides closing one end of'the container 14acts as a follower to eject the ease.

The diameter of the inside of the container 14 is thesame as the outsidediameter of the threads 13 of the grease gun 10 and when it is desiredto fill the grease gun 10 the cap 15 of the container is removed and theopen end thereof screwed onto the open end of the 10, the1soft coatingof tin or lead or the ike taking hold of the threads 13 sufficiently to,temporarily connect the container 14 to the grease gun 10. 'Ihe cap,plunger and the rod of the grease gun have of course been previouslyremoved from the gun.

With the end of the contalnern screwed i tainer.

onto the open end of the gun 10 the grease contained in the containermay now be ejected from and into the gun 10. vTo accomplish this thedisc 18l is forced through the container in the direction. of the gunand consequently ejects the grease from the container. The movement ofthe disc18 may be accomplished by placing the"plun ger of the gun whichhas previously been removed or a hammer-handle or other convenientarticle against the. disc and pushing the same inward "thus completelyejecting all of the grease contained within this con- After the contentsof the container have been transferred to the gun the same is yunscrewedfrom the end of the gun 10 and discarded. The plunger and cap of the gunmay then be replaced thereby tting the gun for further use. Obviouslythe operation has been accomplished Without soiling the hands of theoperator or wasting any of the grease.

In Fig. 3 I have shown a modified construction for the endfof thecontainer 14.

Instead of bending the end back as at 17 of bviously various changes inthe details of construction may be resorted to, it being essential onlythat the movement of the disc 18 be limited in its outward movement sothat it will be maintained in position adjaquantity of grease to dast aconsiderable length-of time. Thus a person can pur- Obviously in fillingthe chase a container of grease and keep the same for instance under theseat of his automobile, the supply being sufficient in most instances tolast a year.

From the foregoing it is obvious therefore that my inventioncontemplates means for storing or carrying grease and a method oftransferring the grease to grease guns. The illustration in the drawingsof several structural modifications is evidence of the fact that4various changes may be made in the details of constructions withoutdeparting from the spirit and scope of my invention and to this endI'reserve the right to make such changes Yas may. come within thepurview'of the accompanying claims.

Having thus described my lnvention what I claim is:

1. A grease container comprising a container body and a layer ofmaterial softer than said body arranged at the end thereof whereby saidcontainer may be connected vto a grease gun or the like by screwing thesame onto vsaid gun.

2. A grease container for use in combination with a grease guncomprising a tubular body, a removab e cap covering one end of saidbody, a displaceabledisc closing the other end of said body, a. softcoating material applied to the inner circumference of .one end of saidlbody whereby it may be threaded upon the end of the grease gun,

the contents of the container being ejected by longitudinally displacingsaid disc.

3. A container of the class described for use in combination with agrease gun comrising a tubular body, the inner circumerence of said bodyat the front end thereof being coated with a soft metal, a removable capcovering this end of the body, a stop forme on the rear end of saidbody, a cupped disc closing this end of said body and abutting"v saidstop, said container being adapted to'be connected to said gun byscrewing rthe front end thereof onto the open end of the gun,'the coatinof soft metal enga ing the screw threa s of the container, t e contentsof the container beng forced into the gun by displacing said isc. f
